TO ALL WHOM IT MAY CON CERN:

I Be it known that Iyl). CYRUS HO'LDRIDGE, of Lodi, in the .county of Columbia, and State of Wisconsin, have invented certain new and useful Improvements in the Point of Iron Tubing for Wells; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being hadto the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

' To enable others skilled in the art to construct and' use my invention, I will proceed to describe it.

My invention relates to an improvement in the construction of. the lower end or point ofthe iron tubing or shaft driven into soil suitable for the purpose of obtaining water. In the drawings- Figure 1 represents a plan view of the point when arranged for being driven into the ground.

Figure 2 represents plan Vview of the point after being driven into the ground and ready to receive the water.

Figure 8 represents a transverse section on the line :l1-:z: of iig. 1.

I construct the point B of wrought iron, of any required length and diameter, tapering or conical-shaped v at the lower end c, and openpat its upper end d. Inj this point I make two longitudinal key-slots C, -on opposite sides of the point'Bfand .having transverse continuations or notches e at their upper ends, as shown in figs. 1 I

. i and 2. In these figs. 1 and 2 the notches e are shown as turning only one way, but 1t is obvious they may be turned both Ways. And in construction for practical operation I usually make them turned both ways- Within this point I place a screw,f, made of* any suitable material, such as sheet ironor other metal of tubular form,

and so as to move easily within the point B. Thisscrewf, provide with slots similar to those in the point B,

but without any notches at their upper ends. After placing the screwfwithin the point B, I pass them over the end of the iron pipe A, which is of suitable size to allow them to work and turn easily upon it; and then pass an iron rod, g, transversely through them, and make a head, z, on either end, by rveting,.or by means of a nut and screw, as shown in iig. 3. The portion of the bolt g between head 72 and the inner tube A may be either square, round, or oblong, and forms a. nick made of suitable size to slide in the slots C and notches e. Now,

when the heads. L are on a line with the slots C in the'point B, and in thescrew f, the pipe A can be shoved down till the heads 7i reach thel lower ends of the slots C, and when in that position the inner pipeA will entirely close the slots. After the point B has been driven as far into the ground as is desirable, the pipe or inner tube A may b'e drawn up till' the heads L reach the upper end of the slots C, and then,by turning the pipe A, the screwf will turn with it, as there are no notches in it corresponding with those in the point B, and in turning,

its perforated sideswillbe placed opposite the slots C in the poi-nt B, so that the water can pass readily through the screwj` and into the pipe A. After the water4 enters the pipe A it can be pumped out, It is obviousthat my improved point may be used in connection with the pipe A in open wells that fill up rapidly, as well as in sandy, marshy, or other light soils.

Having thus described my invention, what I claim is The tubular point B and screwf, in combination with the pipe A, when arranged to operate as described and for the purposes set forth. Y i
